Abstract
The current project is on the abrasive wear and frictional behavior of metals like Aluminum (Al), Mild steel (Ms), Copper (Cu) materials sliding against the stainless steel at counter-face under dry conditions. The parameters are investigated in this project. The metals sliding on each other different sliding speed, loads applied and the durations are examined in order to find out the surface topologies and the wear in different metals.
Block on ring testing machine is used in this experiment in which rubbing and sliding of metals can been seen on the block on ring test machine. In this process, grinding of the metal specimen takes places when weights are added to the machine. At different time intervals, the frictional behavior of the specimen changes due to the contact between the surfaces. Experiments are conducted considering the surface topologies, frictional behavior, operational parameters and performance of the metal. Among mild steel, copper, aluminum and brass, aluminum and brass exhibit better wear. Two-body and three-body abrasiveness of the metal specimen can be seen in this phenomenon.
In additional to the current project, we will discuss the influence of dry conditions that are in contact to the metal surfaces. Building up the specimens and testing the performance of the metals under dry contact conditions helps in analysis of the specimen at different sliding speeds. Applied load, time and frictional behavior are the three parameters in which the entire experiment is based. Using the steady weights 15N, 25N, 35N and 45N the experiment is started for 4 different metals and weights before and after the experiment are noted in a tabular column. The final process is the study of abrasive performance of the metals under scanning electron microscope in which its wear and tear is clearly studied which helps if further research on metals.
